Question

Each step of a metabolic pathway has a

• A. Cofactor
• B. Enzyme
• C. Coenzyme
• D. One to several enzymes

Answer 1

The correct option is B Enzyme

The metabolic pathway has two basic steps anabolic and catabolic reaction. The anabolic reaction includes formation of large complex from simple complex. The catabolic reaction includes breaking of large complex into simpler compounds. Anabolic and catabolic reactions are catalyzed by different enzymes. But each step in a metabolic pathway irrespective of catabolism or anabolism are catalyzed by a single enzyme.

So, the correct answer is option B.
